The simulation resource model of the use of infrastructure of RZD JSCo (AS PROGRESS) is designed to assess the possibility of ensuring planned transportation volumes with consideration of the carrying and processing capabilities of the infrastructure of RZD JSCo (including the volume of repair and construction work) and providing traction resources; it is constantly operated in the domain of the Central Directorate, a branch of RZD JSCo (CD), which includes the railway network of RZD JSCo.

The main purpose of the functional development of the Simulation Resource Model of the use of RZD JSCo infrastructure under the conditions of scheduled freight train traffic is to provide information and analytical support for planning the volumes of freight and empty cars for the coming year,and produce estimated train correspondence for the development of a standard freight train schedule balanced with the capabilities of the infrastructure and traction resources of RZD JSCo and the scope of repair and construction work.

The objective of the system functional development is to create tools to assess the feasibility of the transportation process under conditions of scheduled freight train traffic.

Objective fulfillment criteria include the possibility to use the system for:

• Assessment of the feasibility of forecast railcar traffic for the coming year given the limitations of infrastructure and traction resources
• Generation of estimated train correspondence for the development of the standard freight train schedule, with consideration of the variant modes of direction of car traffic (taking into account the allocated calendar periods of repair, construction and installation work, as well as intensive passenger traffic on the specified directions)
• Estimates of the size of train correspondence expected to run on specialized schedules and the possibility of planning these schedules for specialized freight trains

AS PROGRESS is used for process flow automation (in terms of functional development) of the Central Directorate of Traffic Control, a branch of RZD JSCo.

The Central Directorate uses the AS PROGRESS to distribute annual loadings by months on the basis of the current year's volumes, adjusted for the new transportation parameters provided by the Corporate Transport Service Center.

For the Central Directorate of Traffic Control and the Center of Corporate Transport Services AS PROGRESS generates a consolidated assessment and an assessment by destinations of the ability to cope with the projected car traffic, as well as a list and disposition of bottlenecks within the infrastructure.

Functional development of the simulation resource model of the use of RZD JSCo infrastructure under the conditions of scheduled freight train traffic would enable significant reduction in the amount of technical work associated with the receipt and preparation of information, increasing the validity of decisions made on the basis of simulation of the movement of car traffic through the infrastructure of RZD JSCo.

As part of the functional development, AS PROGRESS provides for the estimates of train traffic by destinations with weight and length standards based on the simulation of the estimated car traffic on the infrastructure of RZD JSCo under the conditions of passing of freight trains as per schedule.

Following the results of estimates, it is determined as to whether it is possible to support the set amount of freight traffic with the available (specified) resources of the network of RZD JSCo.
